Definition of autosampler : a device that automatically loads collected samples (as for spectroscopic or chromatographic analysis) into a laboratory instrument New autosamplers â¦ have contributed substantially to the advancement of combinatorial chemistry, because the increased speed and decreased sample amounts have considerably reduced the cost of experiments. âTerrance A.
